Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television

1 Answer

White vertical lines like jail bars

After warms up, first get some lightly black vertical lines on part of the screen, fade in and out. After long play, bright white vertical lines appear like jail bars. Turn off and cool down, vertical lines go away until tv on for about an hour. See other have same problem and may need DMD Board, BP94-00478a. All sources say it is not available. TV 10 years old, replace color wheel and light two years back. Is it worth repairing? I think not??

    I googled the DMD board and no one has it or it costs over $500. I can buy a new 42 inch new flat screen tv for this. So repairing a 10 year old DLP tv is out of the question. I will pull the light bulb and color wheel out and post for sale cheeply on the internet. Thanks for your replies.

SOURCE: black and white picture only

The color wheel is not the problem. If the spinning color wheel is impaired in its RPMs it will cause picture distortion, not black and white picture. If the color wheel looses any of its color fins, like if it is broken, there will be a loud vibrating noise inside the tv which you did not mention. Also if the color wheel is broken and doesn't spin, the tv will not start up.

The likely problem is on the digital control board or the power supply and should be referred to a local repair shop for repair.

There is an outside chance that you will receive color if you experiment with using all of the different input ports to see if you can find one that will bring back color.

SOURCE: screen dim, black has green in it, contrast and brightness = shin

Since you have replaced the Color Wheel, it sounds like you have not adjusted the Index Delay in the service menu. First reset all of the picture settings you have adjusted back to original factory settings. Then on your Samsung TV Remote and with the TV OFF, Press Mute,Power,123. This will turn on the set and put you in the Service menu. Look for the top setting and select or scroll to the OPTION setting and select and look for INDEX DELAY and select that. Once you have the Index Delay selected use the right and left buttons on the remote to adjust for a picture the has no abnormal coloring and while looking at a program adjust for when the blacks look black with no abnormal coloring. Once that is done, turn off the set then turn the set back on. Now the picture should look normal.

Our Toshiba Regza LCD TV has developed a thin white vertical line down one side and a green horizontal line across the middle. The bottom half of the TV screen then comes and goes in muted and faded...


Hello,

All Plasma and LCD TV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken . Good luck in solving the problem....

Most likely it's graphic card problem, but also may be monitor itself. First, check the signal by connecting to TV (if yours has a PC input), then replace card if that shows the same.
